Rapid detachment of hydrogen bubbles for electrolytic water splitting driven by combined effects of Marangoni force and the electrostatic repulsion
Electrolysis efficiency is significantly hindered by the bubbles on the electrode surface.
Therefore, understanding the bubble evolution process is vital to achieve faster detachment …
